Hi Netope 

As PijushRoy  mentioned, you can use conditionfal formatting.

You can refer to the following sample.

2.I create a matrix and put the following fields to the matrix.

3.Create a measure to set the condition of the color.

MEASURE =
VAR a =
    SELECTEDVALUE ( 'Table'[BP Number] )
VAR b =
    SELECTEDVALUE ( 'Table'[Number] )
RETURN
    SWITCH (
        TRUE (),
        a = 0
            && b = 0, "grey",
        a = 1
            && b <= 1
            || a < 1
            && b = 1, "red",
        a = 2
            && b <= 2
            || a < 2
            && b = 2, "yellow",
        a = 3
            && b <= 3
            || a < 3
            && b = 3, "green"
    )

Then put the measure to the conditional formatting of the value field.

Output
